Problem with H2 and bukkit

Bukkit version: git-Bukkit-1.3.1-R2.0-b2340jnks
I'm trying to use H2 with my plugin but can not seem to get it to work, i've tried both examples on H2 site using

Code:

Class.forName("org.h2.Driver");
Connection conn = DriverManager.
    getConnection("jdbc:h2:~/test");
conn.close();
 
and
 
import org.h2.jdbcx.JdbcConnectionPool;
 
JdbcConnectionPool cp = JdbcConnectionPool.
    create("jdbc:h2:~/test", "sa", "sa");
Connection conn = cp.getConnection();
conn.close(); cp.dispose();

The first one throws java.sql.SQLException: No suitable driver found for jdbc:h2:~/test and the second one throws some error about no class defention found for jdbcx.jdbcconnection pool. I am assuming it can not find H2.jar, but i have put it in bukkits root dir and also /lib. Also when testing it without bukkit it works fine.
